Here we report a phenomenon of metal-organics nano-porous trapping that occurs via intercalation of high-molecular
components of oil disperse system. Metal-organics, particularly porphyrines that are part of asphaltenes and resins may
replace water molecules in nano-porous while intercalating in formation or substrate material - whatever it is clay,
minerals or high porosity substrate. Such processes are naturally occurs in oil sands, specifically in so called poor grade
oil sand ore that has relatively low mass concentration of bitumen. Mass concentration of trapped metal-organics
strongly depends on surface characteristics, porosity and volume of nano-porous material. It may happen that practically
all metal-organics such as vanadyl porphyrine contained asphaltenes are trapped in nano-porous. Therefore nano-porous
metal trapping provides three benefits at once: first, it makes crude oil or bitumen practically vanadium and other metals
free. Second, crude oil or bitumen after such asphaltene intercalation may contain much more of lighter fractions of
carbohydrates and much less asphaltenes and resins then initial crude or bitumen. Third, nano-porous materials were
metal-organics have been trapped is highly enriched ore for mining of V, Re, Mo, Ni etc metals.
